This paper proposes a design of power system control in the hybrid electric vehicle. It adopts the isolated DC/DC power converter as the front-end fuel cell and Lithium-ion battery to supply constant voltage. By micro-controller to detect the hybrid power output, and the low-pressure hydrogen storage temperature, and the adjustment of the power output ratio to provide the energy for loading bal...

The cations and anions of the title salt, 3C(6)H(16)N(+)·HSO(4) (-)·SO(4) (2-), are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network. The hydrogensulfate ion, with a single S-O(H) bond of 1.563 (2) Å, forms a short O-H⋯O hydrogen bond [O⋯O = 2.609 (2) Å] to the sulfate ion. The hydrogensulfate ion accepts two hydrogen bonds from two cations, whereas the sulfate ion, as ...

In this study, oxidation of some 3,5-diacyl or 3,5-diester 1,4-dihydropyridines to corresponding pyridine derivatives using sodium bromate in the presence of NH4Cl, NaHSO4 and Bu4NHSO4 under thermal conditions has been investigated. The yield and structure of formed products is similar under all conditions; however, the reaction is accelerated in the presence of Bu4NHSO4 and NaHSO4. In addition...

The knowledge of pseudothrombocytopenia (PTCP) is important for the accuracy of a clinical assessment and for avoiding unnecessary treatment. An elderly patient was hospitalized with left lung pneumonia. Severe thrombocytopenia [platelet (PLT) number: 18 × 109/L] without any clinical bleeding was found in ethylenediaminetetraacetic acid blood collection tube. PLT measurement was repeated in var...

Lithium concentrations in the serum of patients undergoing therapy with lithium salts were measured by atomic absorption spectroscopy. Serum was diluted 10-fold with water. Physiological amounts of sodium and potassium were included in the blank and standard solutions because these cations enhance the lithium signal by 2%. Calcium, magnesium, bicarbonate, sulfate, and phosphate at the concentra...

The anion-binding properties of two tripodal-based hexaureas appended with the m-nitrophenyl (1) and pentafluorophenyl (2) groups have been studied both experimentally and theoretically, showing strong affinities for sulfate over other inorganic oxoanions such as hydrogen sulfate, dihydrogen phosphate, bicarbonate, nitrate, and perchlorate. The structural analysis of the sulfate complex with 1 ...

oil exploration and production zones are very frequently contaminated with petroleum hydrocarbons or its derivatives. the most important exploration and production zones are located in south-west and south of the country, in iran. masjed soleiman city is located on an oil field. the soil of this region has been affected by the petroleum composition. mach petroleum seepages and springs (asphalt,...

Results of renal function tests done on 36 patients on prophylactic lithium treatment are compared with those of 28 age matched individuals, also being treated for affective disorders but exposed only to neuroleptics and/or tricyclic antidepressants. 25% of the lithium treated patients had A.D.H. resistant concentration dysfunction resulting in polyuria and polydypsia. Serum lithium levels had ...

Zirconium-based alloys are widely used in the field of nuclear industry as cladding for nuclear fuel in power plants. In a pressurized water reactor (PWR), boric acid is added in the coolant for reactivity control. Lithium hydroxide is added to render the coolant slightly alkaline, which helps to inhibit corrosion product deposition on the fuel cladding and reduces the corrosion rate of structu...
